95  * little different than Linux, so it turns out we don't need them.  Some cards

97  * belief that all the entries in Linux don't actually need to be separate there
98  * either, but they persist since it's hard to eliminate them and retest on old,
99  * possibly rare, hardware.  Despite years of collecting ~300 different PC Cards
100  * off E-Bay, I've not been able to find any that need CIS3/CIS4 to select which
